It Makes a Difference to the Sheep

The DPRK announces that it is shutting down the Yongbyon plant, a development which presumably would make it easier to reprocess spent fuel rods to make more nuclear weapons-grade material. Of course the DPRK has previously claimed to have reprocessed all 8,000 fuel rods that were previously kept under IAEA lock and key. It isn't clear how much more material Yongbyon could have generated in the last couple of years. (Thanks to an eagle-eyed student for pointing this story out to me).
